Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618042, here are decompositions:

109 + 8617933 = 8618042
523 + 8617519 = 8618042
661 + 8617381 = 8618042
709 + 8617333 = 8618042
751 + 8617291 = 8618042
1051 + 8616991 = 8618042
1123 + 8616919 = 8618042
1129 + 8616913 = 8618042

Showing the first eight; more decompositions exist.
